How to Download Torrent without a Telegram bot

What is the relationship between Google Drive and Google colab?

Google Colab is a cloud-based platform that provides free access to computing resources and Jupyter notebooks for data analysis, scientific computing, and machine learning. It is based on Google's infrastructure and provides users with the ability to run Python code, as well as access to pre-installed libraries and GPUs. Colab is accessible from any web browser, and it also allows for collaboration and sharing of notebooks with others.

How to download torrent files using Google Colab and Google Drive.

First, confirm your security. Because according to Google's Acceptable Use Policy, users are not allowed to support torrents. But don't worry. I suggest you find a way to download torrents using Google Colab and Google Drive.

I recommend using a new Google account or a Google account that you don't use often for this. Downloading/uploading torrent files may leak your sensitive information to third parties.

Now go to Google Colab and create a new notebook. Second, you create a Google Shared Drive.

First, install the libtorrent library by running the following command in a code cell in Google Colab:

  !apt-get update -qq && apt-get install -y python3-libtorrent
  !pip install google-colab

libtorrent is an open-source C++ library that provides a high-performance implementation of the BitTorrent protocol. The library is designed to be portable and efficient, and it can be used to develop BitTorrent clients for a variety of platforms, including desktop and mobile operating systems.

The libtorrent API provides a range of features, including support for both downloading and seeding torrents, distributed hash table (DHT) functionality, support for multiple peers, and support for various protocols and encryption schemes. The API also supports advanced features such as bandwidth throttling, selective downloading, and prioritization of individual files within a torrent.

Libtorrent has been used as the basis for several popular BitTorrent clients, including qBittorrent and Deluge. It is actively maintained and has a large and supportive user community.

Next, mount your Google Drive to Google Colab by running the following code:

from google.colab import drive
drive.mount('/content/drive')

Create a session to connect to the libtorrent client:

import libtorrent as lt

ses = lt.session()
params = {
    'save_path': '/content/gdrive/Shareddrives/Media/Torrent', # Download path
    'storage_mode': lt.storage_mode_t(2),
    'paused': False,
    'auto_managed': True,
    'duplicate_is_error': True
}

Add the torrent or magnet link to libtorrent

link = "magnet:?xt=urn:...."

Always try to use magnet links to download torrents.

You can use ipywidgets and IPython in combination with libtorrent to build interactive interfaces and notebooks for downloading torrents. Here is an example code snippet (you can improve it further) that demonstrates how to create a progress bar using ipywidgets and IPython when downloading a torrent using libtorrent:

from ipywidgets import IntProgress
from IPython.display import display
from time import sleep

handle = lt.add_magnet_uri(ses, link, params)
ses.listen_on(6881, 6891)
progress_bar = IntProgress(min=0, max=100, description='Progress:', bar_style='info') # Progress bar widget
display(progress_bar)

while (not handle.has_metadata()):
    sleep(1)
    continue

torrent_info = handle.get_torrent_info()

file_size = torrent_info.total_size() # Get total size of the torrent
num_pieces = torrent_info.num_pieces() # Get number of pieces in the torrent

pieces_per_unit = 10 # Update the progress bar every 10 pieces
units = num_pieces // pieces_per_unit

for i in range(units):
    start_piece = i * pieces_per_unit
    end_piece = start_piece + pieces_per_unit - 1

    while handle.status().num_pieces < end_piece:
        sleep(0.1)
        progress = int(100 * handle.status().num_pieces / num_pieces)
        progress_bar.value = progress

    if i == units - 1:
        end_piece = num_pieces - 1

    handle.set_piece_deadline(start_piece, end_piece, 0)
    while handle.status().num_pieces < end_piece:
        sleep(0.1)
        progress = int(100 * handle.status().num_pieces / num_pieces)
        progress_bar.value = progress

progress_bar.value = 100 # Set the progress bar to 100% after the download completes

This code uses lt.add_magnet_uri() to add a magnet link to a new session, waits for the metadata to be available, and downloads the torrent while updating the progress bar. The sleep() function is used to wait for some time before checking the status of the download again. Note that this example assumes that you have mounted your Google Drive in Colab and that the download path in params is correct.

To increase the download speed, you can change the type of runtime type. eg: GPU or TPU

What is the Google colab TPU?

Google Colab TPU refers to the availability of TPU (Tensor Processing Unit) hardware accelerators on Google Colaboratory, a cloud-based development environment for writing and running code in various programming languages such as Python, R, and Julia.

TPUs are specialized hardware designed by Google to accelerate machine learning workloads, especially those involving deep neural networks. TPUs are highly efficient and can deliver significant speedups compared to traditional CPUs and GPUs for certain types of machine learning tasks.

Google Colab provides access to TPUs, allowing users to accelerate their machine learning experiments without the need for expensive hardware or local installations. To use TPUs in Google Colab, users need to select a TPU runtime when creating a new notebook and then modify their code to take advantage of the TPU hardware.

Overall, the availability of TPUs on Google Colab can greatly accelerate the development and experimentation of machine learning models, especially for users who don't have access to powerful local hardware.

Google Colab provides integration with Google Drive, which allows users to read and write files to their Google Drive account.

If you download torrents to your Google Drive account, it is still not recommended as it can consume a significant amount of network resources and bandwidth and can also be a security risk. Additionally, Google Drive has bandwidth limits that may be exceeded by torrenting activity, which may result in temporary or permanent suspension of your account. Therefore, be careful not to use your personal account for this.
